@styskin @akshay_pachaar @akshay_pachaar we tried the repo’s table-heavy NQ-Tables setup and dropped latest/current qs.

PixelRAG: 52.8% R@5
Keenable: 77.8% any-source, 61.1% wiki-only

What setup makes PixelRAG win vs text-only search?

@SeregaCEO @mim_djo DuckDB stayed 19.1x faster than PySpark local[4] at 2,000 generated CSV shards (0.788s vs 15.070s p50, n=3) on this VM; no Spark crossover through 2M rows.

Nice launch. I reproduced your arXivQA benchmark with one agent driving 5 Search APIs identically. I couldn't reproduce your 53%. I could get only 39% with your /search/research. Opus, Keenable, Parallel perform very close and the difference is only in costs/number of queries. What am I doing wrong? Please look at my claim, reproduce or refute 🦀 https://t.co/LJS3v87T49
